lvextend

Sridhar R — Sun, 16 Mar 2008 04:26:12 GMT

Hi,

I am in process of extending an LV. I did,

#umount /applbsc
#lvextend -L 81920 /dev/vg00/lvol9
#mount /dev/vg00/lvol9 /applbsc

I was able to successfully extend it and got the message.

But, the bdf was still showing it is 50 GB.

When i checked with SAM, it was showing 80 GB, i tried rebooting the server. Still the bdf output was same.

Now i have a huge tar file of 31 GB which i want to restore in this directory.

What is the exact size of this lvol right now??

Thanks in Advance!
Sridhar

Lvol is of 80 GB but the filesystem is of 50GB since you never extended the filesystem.

You have to extend the filesystem after extending the lvol using extendfs after unmounting the filesystem.

If you have online jfs then it could be done online using fsadm command.

Once filesystem is extended then after mount you will see full 80GB space.

now you need to extened your file system using the command if you have online JFS installed

# fsadm -F vxfs -b M /applbsc

if u have online JFS installed in your machine, you can verify it with

#swlist -l product|grep JFS

and license in 11iv1 is

#vxlicense -p

and 11iv2 is

#vxlicrep

You can use "extendfs" to extend the filesystem offline.

Re: lvextend

Mridul Shrivastava — Sun, 16 Mar 2008 08:11:16 GMT

use /usr/sbin/swlist -l product |grep -i JFS to check online jfs.

Else unmount the filesystem as suggested above and use extendfs.

Hi Sidhar,

As you are not having online JFS Complete process should be:

#umount /applbsc
#lvextend -L 81920 /dev/vg00/lvol9
#extendfs -F vxfs /dev/vg00/rlvol9
#mount /dev/vg00/lvol9 /applbsc

Assuming your lvol9 FS is vxfs.

Dear Sridhar

first u have to clear online jfs is installed or not
swlist -l product | grep -i jfs

once it is installed u can extend the file systm by usning fsadm without unmount
if u are extending logical volume u extending logical volume only not file system
if u want to extend file system u have to use fsadm command.

for example if u are extending
a logical volume 5 gb from 2 gb
u logical volume is extende upto 5 gb
but u file system is still 2 gb
this is concept behind it

Hi,

Please do the following steps.
As you have already extended LV. You need to extend file systems also.

# umount /applbsc
# extendfs -F vxfs /dev/vg00/rlvol9
# mount /dev/vg00/lvol9 /applbsc

regards
Kumar

What u did till the below command seems to be good.

lvextend -L 81920 /dev/vg00/lvol9

You just need to unmount the fs now and do extendfs now and remount it. Thats all you need to do now. (This is incase of online JFS not there at your system)
#extendfs -F /dev/vg00/rlvol9
-----------------------
The steps you performed just extended the logical volume but not the fs. Just to be clear here. Keep on further updates if I miss any.
